Hair thickening products are sought after to treat and improve the appearance of fine and thinning hair. There are tons of products out there to choose from, some of which are more suitable than others, depending on the condition of your hair and scalp.

Lots of different things can contribute to thinning hair and hair loss, including hereditary conditions, pulling back the hair too much, overprocessing your hair and much more. Let’s dive into fine hair, thinning hair, why hair loss happens, and what products to use to improve the condition of your hair and scalp.

What causes hair loss and thinning hair?

Hair loss and thinning of the hair can be caused by one or a variety of factors, such as:

  • A hereditary condition
  • Stress
  • Illness and/or medication affecting the hair folicles
  • Alopecia areata
  • Cancer treatment
  • Hormonal changes
  • Dyeing and bleaching hair too often
  • Excessive and tight hair styling.

There are certain things that can increase the rate of hair loss too, such as:

  • Poor nutrition
  • Age
  • Family history of hair loss
  • Significant weight changes.

It’s worth checking with your doctor why your hair is thinning, especially if you don’t use tight hair styles or aren’t experiencing any obvious signs of stress. A blood test can check to see your vitamin levels, but they’ll be able to test for other things if they suspect other reasons for thinning hair.

Do hair thickening shampoos work?

Yes and no.

Hair thickening shampoos aren’t capable of changing the structure of your hair. Your head contains a finite number of hair follicles, which contain a root from which your hair grows from. Some people naturally have less than others, sometimes in places you may find more noticeable, such as your hairline. It’s impossible to use products, including hair thickening shampoos to increase the number of hair follicles on your scalp.

How do hair thickening shampoos work?

Hair thickening shampoos do exactly what they say. They help improve the appearance of your hair by thickening it. It does so by reducing the amount of space in between your strands of hair. 

Hair thickening shampoos will contain chemicals that swell the hair to give it thickness. This comes in the form of protein and panthenol (or some other kind of polymer). The panthenol is responsible for thickening the hair, whereas the proteins will strengthen the outer layer. You may find these hair thickening products contain a variety of scents and moisturisers in there too, to improve the look and feel of your hair.

What is the difference between thickening shampoo and volumising shampoo?

In simple terms, volumising shampoo adds lift, and thickening shampoo reduces the space between hair, making it look thicker.

Thickening shampoos work by infusing your hair with proteins, moisturising ingredients and polymers to thicken it. It’s favoured by those with fine hair, but too much of a good thing can be detrimental, so use it sparingly. 

Volumising shampoo, on the other hand, focuses on the scalp. This is so lifting is created from the top of your head, hence creating a voluminous appearance to flat hair. There’s little to no residue or build-up too. Volumising shampoos incorporate ingredients to enhance follicle structure, maximize lift, and clean without leaving residue build-up. These come in the form of oils, caffeine, herbs and other natural ingredients like bamboo or sage to manage oil production (which contributes to flat hair).
